医学检查中的INR指的是从凝血酶原时间(PT)和测定试剂的国际敏感指数(ISI)推算出来的。 INR中文称为国际标准化比值。采用INR使不同实验室和不同试剂测定的PT具有可比性,便于统一用药标准。 INR为国际标准化比率(International Normalized Ratio)的缩写。用凝血活酶所测得的参比血浆与正常血浆的PT比值
To evaluate the electro- chemical properties of CBS Pt-Pd nanoparticles for ORR and their methanol tolerant property at room tempera- ture, both the CBS Pt-Pd nanoparticles and Pt seed nanoparticles were loaded on Vulcan carbon substrates with mass ratio of 20% (Pt base), labeled as ...

We propose a four-tiered grading system based on mitotic count (> 10/10 high-power fields), nuclear pleomorphism (smallest-to-largest ratio of tumor nuclei >20), presence of divergent histology, and capillary proliferation (> 20 capillary lumina per papillary core). The level of mitoses at ...

凝血酶原活动度(PTA)是指肝病(PT)的传统报告方式,虽然受到了科学性的质疑,但相对于肝病的病情评价、分类诊断等具有十分重要的参考价值。长期以来,作为实验过程中对血液几乎不造成稀释,也就不会出现稀释比例改变的问题存在。我们分析比较使用 EDTA 抗凝时所测得的(PT)、(INR)、(PTA)结果与枸橼酸钠抗凝时的相关性...
Thus, the ambition to develop low-Pt-loading cathodes poses great challenges in the areas of Pt utilization and the intrinsic durability of Pt-based electrocatalysts. Despite great efforts in the development of advanced Pt-based catalysts to improve the Pt utilization and mass activity (MA) ...
Very high carbon to metal atomic ratio are observed, which shows that the metal enhances the deposition of carbon also on the support. This can be explained by the fact that the surface compounds come from reaction products of aniline favored by the catalysts themselves. Most likely, the ...
the induction ratio exceeded the critical ratio of 1.5 at a PTA concentration of 46 +/- 16 microg/ml and, in tests without S9, the critical ratio was exceeded at a PTA concentration of 279 +/- 22 microg/ml. CONCLUSIONS:The genotoxicity of PTA is comparable to that of quercetin, anothe...
Surprisingly, the obtained ratio between BMO and CN from TGA result is higher than the theoretical value of 20%, which is mainly attributed to the existence of BMO and Pt would promote the oxidation of CN and the adsorption of atmospheric oxygen. Similar junction photocatalysts. performance has ...
